LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 493,727, dated March21, 1893. Application led July 20, 1892. Serial No. 440,628. (No model.)

To all whom it may concern:

Be it known that I, CHARLES C. JEROME, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Lubricators; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled inthe art to which it appertains to make and use thesame.

My invention relates to an improved automatic force feed oil cup,-theobject of the invention being to construct the device in such mannerthat leakage of the oil therefrom will be effectually prevented.

A further object is to provide a simple automatic force feed which willonly feed the oil when the machine to which it is applied is inoperation, and which then forces said oil directly to the spot whereverit may be led by a pipe or otherwise. t A

A further object is to provide an oil feed device by means of which theoil will be positively fed at certain intervals, without waste of oil.

A further object is to so construct the device that the feed may beeasily and quickly regulated.

A further object is to produce an automatic force feed which shall besimple in construction and effectual in the performance of itsfunctions.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts ashereinafter set forth and pointed out in the claims.

In the accompanying drawings: Figure lis an elevation of my improvedautomatic force feed. Fig. 2 is a vertical sectional view.

A represents the cylinder or cup, in the center of the bottom of which arecess a is formed, and in the center of this recess an outlet opening bis made.` At opposite sides of the recess a, flanges c project upwardlywithin the cup and serve to receive between them flanges c projectingfrom diametrically opposite sides of a plunger B, whereby to guide saidplunger in its movements as hereinafter explained,- the head d at thelower end of said plunger being adapted to enter the recess a in thebottom of the cup and normally close the opening b. Immediately abovethe Iianges c of the plunger B, is a circular disk e which is normallydisposed in proximity to the tops of the flanges c projecting from thebottom of `the cup. The plunger B is of a length suf- `cient to projectabove the top of the cup B, and is encircled by a coiled spring C, the`lower end of which bears against the disk c,

and the upper end against a cross bar f,

`through which said plunger passes,-said cross bar being prevented fromupward movement or escape from the body of the cup, by

means of inwardly projecting flanges f located at diametrically oppositepoints at the top of the bodyof the cup. By means of the spring C theplunger head d will be normally held down to its seat.

Projecting from the bottom of the cup A and communicating with theopening a, is an outlet pipe or stem g, which is screwthreadedexternally for the reception of a suitable coupling whereby to attach apipe to the lubricator to convey the oil to the desired point. At. theupper end of the pipe or stem g, a conical seat h is formed for thereception of a conical valve D adapted to enter the outlet opening a.The stem i of the conical valve D enters one end of a, preferablyconical, coiled spring j inserted in the pipe or stem g, said springbearing at its other end on a plug j', screwed into the end of the pipeor stem g, said -plug being `provided with an opening jz for the passageof the oil from the cup. The spring j tends to force the conical valveI) to its seat to close the opening c.

The upper portion of the cup A is contracted somewhat on its exteriorand has loosely fitted on it, a cap or top E, the lower edge of said capresting on the shoulder ,lo of the cup. The cap E is provided centrallywith a perforation for the accommodation of the plunger B, and inproximity to said perforation a cam Z is made on the cap E, for apurpose which will presently appear. An inlet m for filling the cup ismade in the cap E, and normally covered by a spring cap plate m',pivotally attached tothe cap E. The upper end of the plunger B isscrewthreaded for the reception of a nut n, on the under face of which acam Z is made and adapted to be engaged by the cam Z on the cap E. Inproximity to the periphery of the cap E and extending entirely aroundthe same, is a se- IOO ries of teeth F adapted to be engaged by a dog G,pivoted in the bifurcated end of a lever I-L-which latter is pivotallyconnected to the bifurcated upper end of an arm 0 projecting laterallyand upwardly from the cup A,-the pivotal connection of said lever beingin proximity to the pivotal connection of the dog G thereto. From'itspivoted connection with the arm 0 the lever H projects outwardly anddownwardly, preferably in a curved line, and at the end of saiddownwardly projecting portion is provided with an elongated slot p,through which a rod q projecting horizontally from the arm o, passes. Aspring rr' encircles the rod q, bearing at one end on a shoulder fr inproximity to the arm 0 and at the other end on the lever H or a washerr2 interposed between said spring and lever. The rod Q is providednearits free end with a series of perforations s for the reception of akey s', and by shifting said key from one perforation to another thetension of the spring may be readily regulated. From the ybase of theelongated slot p, the lever H projects laterally, then downwardly andthen inwardly, so as to adapt it to be connected to the cross head of anengine. The free end of the lever H may be otherwise formed, should itbe desired to connect it with some other moving part of the engine, itbeing only necessary to so connect it with the engine, that when thelatter is in operation said lever will he vibrated to cause the dog G toengage the teeth F on the cap and thus rotate said cap, step by step.Thus it will be seen that by vibrating the lever H the dog G will engagethe teeth F of the cap, and that every time the cam on the cap comes incontact with the cam on the nut n, it causes the plunger B to rise, thusallowing the oil to iiow under its head. .When the cams Z, Z release theplunger, the spring C inside the cup causes it to be forced down andopen the conical valve D in the bottom of the cup which allows the oilto be forced out by the head of the plunger to wherever it may be led bymeans of apipe or otherwise.

One great point of merit in this cup is that it never leaks any oil andonly feeds when the engine is running and then forces the oil directlyto the spot wherever it may be led by pipe or otherwise. The feed isregulated by moving the pin s from one perforation to another in therodl q as above explained thus allowing the dog G to feed three notchesor less according to the position of the pin s and as the cup feedsevery time the cams come together or meet, the more notches the dogfeeds at a time, the oftener the oil will feed. The feed can also beregulated by increasing or diminishing the size of the cams, thusallowing the plunger to be raised higher or not so high as the case maybe, and the higher the plunger is raised the more the oil flows underit,--and thus the amount of oil fed at a time is regulated.

The device is very simple in construction,

not easy to become clogged or get out of order, and is effectual in theperformance of its functions.

Slight changes might be made in the details of construction of myinvention without departing from the spirit thereof or limiting itsscope, hence I do not wish to limit myself to the precise details ofconstruction herein set forth, but,
